When crawling up parent URLs trying to find repos-global information (such as the WebDAV VCC), tolerate 403 Forbidden responses.  It might be that some parent directory of the unreadable thing is itself readable, which gives us a better chance at finding the information we need.  (Similar to r1066898, which made this change in libsvn_ra_neon.)

* subversion/libsvn_ra_serf/util.c
  (svn_ra_serf__discover_vcc): Tolerate SVN_ERR_RA_DAV_FORBIDDEN, too,
    in our upward crawl towards a readable parent.  But reset the Serf
    connection before reusing it!
